mpls vs ipsec

Security has always been a concern of our network applications, so we also have protocols in terms of protocol support. Now let's take a look at the IPsec protocol. This security agreement was proposed by Cisco. The IOS Implementation of Cisco's IPsecInternet Protocol Security) suite is an open-standard framework that provides administrators with tools for communication over Secure IP networks. The IPsec fr

Application introductionIPSec VPN can be used to establish a secure tunnel between two sites and is often used for network interconnection between enterprise headquarters and branches. This paper takes a company in Beijing headquarters and Guangzhou Branch need to build a security tunnel for example, introduces the use of TL-ER7520G to build IPSec VPN settings.Note:The preceding parameters are for example only. The actual network parameters shall prev

VPN!--Special Portal IPSec principle Description: IPSec is the short name for IP Security, which is designed to provide high safety features for IP, and VPNs are solutions that are generated in the way that this security feature is implemented. IPSec is a framework structure that consists of two types of protocols: 1, AH protocol (authentication Header, less

This site has previously shown us the method of segmenting a router into eight virtual routers using virtual Routing and forwarding (VRF, VM forwarding) through a scene example. I showed you how to configure VRF, and in this article we continue to use this scenario and, through IPSec configuration, replicate the exact topology and address to eight experimental environments. The entire environment can proceed smoothly, first requires the virtual route

communication and encapsulates it in the IP header sent across the company's IP network or public IP network (such as the Internet. Ii. L2TP Layer 2 Tunneling Protocol (L2TP) is a later version of PPTP developed by IETF Based on L2F (Cisco's L2 forwarding protocol. It is an industrial standard Internet tunnel protocol that provides encapsulation for a Point-to-Point Protocol (PPP) framework that spans data packets. Both PPTP and L2TP use the PPP protocol to encapsulate data, and then add additi

As a new VPN technology, ssl vpn gateway has its own unique characteristics and has its own merits. Ssl vpn is suitable for mobile users' remote access (Client-Site), while IPSec VPN has inherent advantages in Site-Site VPN connections. These two products will coexist in the VPN market for a long time, with complementary advantages. In terms of product performance, the two products have the following differences: 1.

Caution Against Ping with IPSec security policy The use of IPSec security policy "ping" is a common method, after a simple step of IPSec security policy configuration, you can achieve the effect of ping. This method is relatively simple to configure, and IPSec security policy is a feature that is built into the Window

Many people asked me how to implement the IPSec VPN Technology Based on the router. I used this case to explain how to configure an IPSec VPN based on the router. Due to work requirements, it is required to establish a VPN connection between the company's Nanjing office and the Shanghai office. Network settings of Nanjing Office: Intranet IP address 10.1.1.0/24, Internet IP address 202.102.1.5/24, Intranet
